Nirmal Purja
Nirmal Purja is a Nepal-born naturalised British mountaineer. Prior to taking on a career in mountaineering, he served in the British Army with the Brigade of Gurkhas followed by the Special Boat Service (SBS), the special forces unit of the Royal Navy. Purja is notable for having climbed all 14 eight-thousanders in a time of six months and six days with the aid of bottled oxygen between April and October 2019. This was a record at the time of climbing, although it was broken in 2023 by Kristin Harila and Tenjen Sherpa, who summitted all 14 eight-thousanders in 92 days. Purja was the first person to reach the summits of Mount Everest, Lhotse and Makalu within 48 hours. In 2021, Purja, along with a team of nine other Nepalese climbers, completed the first winter ascent of K2.
